- Lab cells

- Review
- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was only tested on cells in a lab and in mice.
The short version
Scientists tested a new wireless way to attack glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary cells, so far only in the lab and in mice.
What was studied. Researchers made tiny particles that turn a magnetic field into a small electric charge right at the tumor. They tested this on tumor cells taken from patients and grown in a dish, and in mice with brain tumors.
What they found. In the lab, the treatment cut the number of living tumor cells by 52.2%. A common chemo drug called temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary cut them by 10%. The treatment left healthy brain cells alone. In mice, it slowed tumor growth and helped them live more than 50% longer. It did not seem to harm the rest of the body.
What this means, and what it doesn't
What it could mean: This is an early idea for a new way to fight glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. The researchers hope it could one day kill tumor cells while sparing healthy ones. It worked on tumor cells that did not respond well to drugs. Much more research is needed before we know if it helps people.
What it doesn't mean: This was only tested on cells in a dish and in mice. It has not been tested in people yet. What works in mice does not always work in people. It is not a cure. It is not something a doctor can offer you today, and it may be many years away, if it works at all.
